People have heard of film production horror stories where actors and actresses refuse to get along and create unnecessary drama on the set. But it seems like Disney's live action movie Beauty and the Beast won't be suffering from that setback.

To make her new co-stars feel welcome, Harry Potter alumna and UN ambassadress Emma Watson tweeted greetings to Luke Evans and Dan Stevens, who will be playing Gaston and Beast, respectively.

In her Twitter account, Watson posted a picture of Evans and wrote, "Bonjour Gaston! Welcome!"

As a reply, Evans posted a picture of himself and an animated Gaston and tweeted, "Why thank you Belle!"

Evans gained recognition for playing Bard the Bowman in The Hobbit trilogy. His character bravely defeated the arrogant dragon Smaug, therefore gaining the respect of his villagers. While Bard was a protagonist, Evans has taken on some villainous roles too. He was the antagonist in Fast and Furious 6 and he also played the titular role in Dracula Untold.

Meanwhile, Watson posted a wacky shot of Stevens on Twitter and said, "Could not be more happy that this man will be Beast!!! Welcome aboard."

Stevens gave a short but witty reply: "Grrrrrr."

Stevens shot to stardom for playing the lead character Matthew Crawley in the British drama Downton Abbey. But the actor decided to move in a different direction with his career and left the show, so they killed off his character after three successful seasons.

Downton Abbey still continues after Stevens' departure. He recently portrayed Lancelot in the last Night at the Museum sequel alongside Ben Stiller and the late Robin Williams. He will also star in Adam Wingard's last film called The Guest.

Watson was the first big name to sign on to Beauty and the Beast. She made the announcement on her Facebook page: "I'm finally able to tell you... that I will be playing Belle in Disney's new live-action Beauty and the Beast! It was such a big part of my growing up, it almost feels surreal that I'll get to dance to 'Be Our Guest' and sing 'Something There'. My six year old self is on the ceiling - heart bursting. I can't wait for you to see it."

It seems like fans will be hearing Watson showcase her singing sklls for the movie since she wrote, "Time to start some singing lessons."

The movie will hit theatres sometime in 2016.
